Two SP4-RMX modules can be ganged together when connecting them to an SP40/2 panel. This provides a maximum of six remote
microphones providing “All Call” for the entire system. One SP4-RMX can be connected to each audio booster providing three non­alarm/general page remote microphones for that audio booster audio output. Each SP4-RMX provides a line level, 600 Ohm auxiliary
audio input.

There are two configurations for the Priority levels of the remote microphones can be set. One configuration sets the priorities as:
RM1, priority 1; RM2, priority 2; and RM3, priority 3. For instance, if RM3 is broadcasting, RM1 or RM2 can override RM3. The
other configuration allows the first remote microphone to broadcast to have the top priority until it completes its message. The remote
microphones operate on a first in – first out basis.

Installation:

The lives of people depend upon your safe installation of the SP4-RMX. Please read, understand and follow the specific
installation instructions set forth below to avoid damage to the SP4-RMX and equipment connected to it. Installation should be
conducted only by qualified persons in accordance with procedures in this manual.

WARNING: SHUT OFF ALL POWER BEFORE STARTING THE INSTALLATION. ELECTRICAL SHOCK CAN

CAUSE DEATH OR SERIOUS INJURY.

CAUTION: The SP4-RMX printed circuit board is sensitive to static electricity and has delicate components mounted on it.
Before handling either a board or any component on a board, discharge any static electricity from your body by touching a grounded
object such as a metal screw which is connected to earth ground. Handle the board by its edges, and be careful not to twist or flex it.

CAUTION: When the SPRM-GP is used on a SP4-RMX and SPB-80/160/320 location, the paging from that microphone will
only be heard from zones that have BGM turned on in the software.

Install the SP4-RMX in a static free area and the user is to properly attach grounded wrist straps before touching any static sensitive
areas. After handling printed circuit boards, the SP4-RMX should be tested in accordance with the “System Checkout” section to
verify that the printed circuit boards are undamaged and functioning properly.

CAUTION: The Authority Having Jurisdiction (AHJ) should be consulted by the installer prior to installation.

Installation Guidelines:

1. Prepare a drawing of the complete system wiring. (Keep copies of the system wiring drawing and this SP4-RMX Installation

Instructions with the SAFEPATH4 panel for reference.) These Installation Instructions shall be made available to all qualified
personnel who operate, test, maintain, or service SAFEPATH4 products.

2. Carefully unpack the SP4-RMX and make sure each item described on the packing slip is present and undamaged.

3. Mount the SP4-RMX in the desired location as described in the "Mounting" section.

4. Mount any additional wiring boxes or junction boxes needed to interconnect field wiring.

5. Connect conduit fittings or bushings as needed using knockouts provided on the top and bottom of the SP4-RMX units (see

Figure 2).

6. Install field wiring in conduit when necessary, following the National Electrical Code and local codes for the type of system

being installed. Make all necessary connections at any additional wiring or junction boxes.

CAUTION: Provide proper strain relief for all wiring not in conduit.

7. Connect the SP4-RMX to earth ground, following the National Electrical Code and local codes for the type of system being

installed.

8. Check the integrity of all field wiring following the directions in the "Field Wiring Checkout'' section. Confirm that the

specified cable is installed and that there is continuity between required points (no open circuits), with no unwanted connections
(shorts) to other conductors, chassis, or earth ground.

9. Connect the wiring to the appropriate terminals of the SP4-RMX modules following the directions in the "Field Wiring" section

and the system wiring drawing you created in Step 1.

10. Set the switches for the proper configuration as described in the “Application” sections.

Wiring Guidelines:

Use shielded twisted pair wire for all audio input and output wiring. Follow national and local regulations for conduit use.

The shield of each cable should be connected only at one end. Each shield of each cable that connects to the SP4-RMX is to connect
to the grounding terminal provided near the right edge of the chassis (see Figure 2).

CAUTION: All SP4-RMX wiring should be routed away from any high voltage or high current lines (such as AC or DC power
lines, audio power lines, and motor or relay actuation lines) and should be installed in separate conduit from high voltage or high
current lines.

The National Electrical Code defines two types of circuits for protective signaling systems: power limited circuits and non-power
limited circuits. All SP4-RMX circuits have been designed as power limited circuits. Do not run power limited and non-power
limited in the same conduit.

CAUTION: The National Electric Code limits the maximum number of conductors that can be installed in conduit and wiring
boxes depending on the size of the conduit, the volume of the boxes, and the gauge of the wire used. Make sure that wiring used
complies with the latest NEC requirements for power limited circuits.

Wiring Specifications:

Between SP40/2 (or Audio Booster) and SP4-RMX

Cable Size: 14 - 22 AWG Shielded. One end of the shield must be connected at the SafePath4 panel or SP4-
RMX enclosure.

Maximum Length: 20 Feet

Restrictions: All wiring between SP40/2 (or Audio Booster) and SP4-RMX must be run in conduit and within
the same room.

Between each SPRM and SP4-RMX

Cable Size: 14 - 22 AWG Shielded. The shield must be connected only at the SP4-RMX enclosure.

Maximum Length: 2000 Feet

Maximum Capacitance: 05uF/Total Run (50pF/foot for 1000 FT.)

Mounting:

The SP4-RMX shall be mounted in a location within the environmental limits specified in the latest UL Standard for indoor control
panels. It shall not be located in a hazardous location. Refer to the "Technical Specifications'' section.

CAUTION: In order to comply with the latest NFPA and UL requirements for interconnection of fire alarm control equipment,
the SP4-RMX unit must be located in the same room as, and within 20 feet of the SAFEPATH4 Panel it is connected to.

Refer to Figure 2 for SP4-RMX mounting hole layout. Drill mounting holes for appropriate screws and anchors to ensure secure
mounting to the type of surface at the selected location. Keep out dust and dirt during installation. Dust and dirt can interfere with
the operation and reduce the life of the equipment.

Remove the outer cover and mount at the selected location. Use care to avoid damage to the PC board during installation

. Do not

apply excessive pressure to the PC board or its components; including field wiring terminals and connectors or damage may occur.
